LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 233,925, dated November2. 1880,

Application filed April 5, 1880.

To all whom it may concern:

Be it known that I, FRANCIS J. FREEsE, of Lawrence, of the county ofEssex and State of Massachusetts, have invented a new and usefulImprovement in Loom-Shuttles; and I do hereby declare the same to bedescribed in the following specification and represented in theaccompanying drawings, of which- Figure l is a longitudinal section of ashuttle provided with my invention. Fig. 2 is a side view, Fig. 3 a rearend view, and Fig. 4 a longitudinal section, of the spindle and itsbobbin-holding appurtenance. Fig. 5 represents a shorter bobbin.

In the said Fig. 1 the bobbin is shown as upon the spindle and downwithin the bobbinchamber of the shuttle, such bobbin and spindle being,by the dotted lines, represented as in a raised position. The spindleand its bobbin-holding devices are somewhat analogous to what isrepresented in Division B of the reissue of the Patent No. 97,882,though there are important differences which relate to the constructionof the spindle and to that of the bobbin-holder applied to the saidspindle.

In the drawings, Adenotes the shuttle-body;

B, the spindle; O, the bobbin; D, the top spring, and E thebobbin-holder. The said spindle B is provided, near its outer end, witha bobbin-holding projection or shoulder, a, while at the base of thespindle, or its junction with the neck of the head I), the spindle isformed with an auxiliary or inclined projection, 0, as shown.Furthermore, the spindle is channeled or grooved, as at d, in its lowerside from near its outer end to and through the neck of the head, andfrom thence there is a hole, 0, which extends from the groove up throughthe head and in front of the pivotal hole f thereof. There is also atthe front end of the groove, and in the spindle, a pivotal recess orsocket, g, to receive the bobbin-holder E and keep it in place inconnection with the spindle. This bobbin-holder is a piece of Wire bowedor curved at its middle and bent near its rear end, in manner asrepresented, so as to extend up through and to or nearly to the upperend of the passage or hole 0 of the head.

The spindle so made and provided with the the bobbixrholder is connectedto the shuttle- (No model.)

body by a pin, t, which goes through such body and the hole f.

On the spindle being turned up to its highest position relatively to theshuttle-body the bobbin can be removed from the spindle, ora bobbin canbe placed on such spindle, in which latter case the bobbin will rest onthe spindle and between and against the neck of the head and theprojection a, provided the bobbin be of sufficient length therefor; butshould it be of less length, as represented in Fig. 5, it, by theinclined projection 0, will be supported at or near its rear end fromslipping back against the neck. On the spindle with abobbin on it beingturned down into the chamber of the shuttle the upper end of thebobbin-holder will be borne downward by the top spring, D, so as toforce the middle of the bowed part of the holder against the bore of thebobbin in a manner to hold the bobbin firmly in place on the spindle,and especially so with the projections a and c, or with the projection aand the neck of the head of the spindle.

Thus it will be seen that I have to the spindle no spring adapted toexpand within the bobbin and hold it within its base. The bobbinholderhereinbei'ore described operates to hold the bobbin at or near themiddle of its bore, and besides such holder, to accomplish such, isborne downward by the top spring.

I am aware that it is not new to have to a shuttle-spindle abobbin-holder like that hereinbefore described, such being shown in theBritish Patent No. 507 for 1866; but in such case the spindle was not,like my spindle, provided on its side with two projections extendingtherefrom and serving to receive the bobbin between them and topreventit from being driven forward or backward on the spindle on theshuttle being stopped in its flight overthe race-beam of the lay of aloom.

What, therefore, I claim as my invention is as follows-viz:

1. The loom-shuttle spindle provided on its upper side with the twoprojections to and c and on its lower side with a groove extendinglongitudinally from near its outer end to and into its head, and havinga passage leading from it (the said groove) up through the said head, incombination with the bowed bobbinholder, as described, arranged in thegroove and pivoted to the spindle and extending upward into the passageof the head and adapted to bear against the top spring, all beingsubstantially as and to operate as set forth.

2. The loonrshuttle spindle, constructed as described--\'iz., with thetwo projections a and c on its upper side, the bobbin-holder recess nearits end, and the grooved, extending from such recess through the lowerside of the spindle and opening through its head at the back thereof,and provided with a passage, 0, to lead upward to the top of the head-incombination with a bobbin-holder, as described,

arranged in the said recess and groove and 15 extended up through thepassage 0, all being arranged substantially as set forth.

3. The combination of the shuttle-body A and spring D with the spindleB, provided with the projections a and a, groove 0?, and 20 passage e,and the bobbin-holder E, adapted to enter groove d and recess a, and beretained in connection with the spindle, substantially
